My 383 with 284/484 build used a Torker intake (which everyone still says not to use despite "the numbers" suggesting otherwise), a Holley 650 DP with a 750 rear metering block setup, and cheap line Hooker headers. Cam degreed as per Mopar instructions with lots of initial dist advance. Carb was the lynch pin and took months to figure out. was getting way too much fuel at idle and not nearly enough at WOT.
Everyone said "too much cam and not enough converter", but it ran GREAT.
